摘要： A piano hammer stopper system includes a blocking rail movable between a first position, allowing unobstructed movement of piano hammers, and a second position, blocking at least one piano hammer from striking any corresponding strings. The piano hammer stopper system includes a drive shaft rotatably coupled to the blocking rail, a drive arm attached to the drive shaft and engaging a drive fulcrum, and a travel guide directing movement of the blocking rail between its first and second positions. Rotation of the drive shaft rotates the drive arm to engage the drive fulcrum for moving the blocking rail between its first and second positions.

摘要： An action in an acoustic piano is provided which can reproduce the touch and feel of the key depression generated in a normal performance mode even in a silent performance mode. The acoustic piano is capable of being switched between the normal performance mode and the silent performance mode. In the silent performance mode, a rotation lever of a transmission switching mechanism disconnects the hammer operating portion from the key. A load switching mechanism is rotated to lower the tip of a weight lever to abut directly upon the upper face of the key. Then, the weight lever swings up and down corresponding to the key depression of a player, closely reproducing the touch and feel of a conventional acoustic piano.

摘要： A combination acoustic mode and electronic mode grand piano is provided including a hammer shank stop rail that intercepts the hammer shank when operating in its electronic mode, so that the hammer cannot complete its normal travel to strike its corresponding string(s) when its key is actuated. The positioning of the hammer shank stop rail is actuated by a user-operated control that, when placed into the "acoustic" mode, raises the hammer shank stop rail to a non-engaged position that does not interfere with the normal movements of the hammer shank. When in the "electronic" mode, the control lowers the hammer shank stop rail into an engaged position where it intercepts the hammer shanks of the piano, thereby preventing each hammer head from striking its respective string(s). When in the engaged position, the wire cam also causes an "early escapement rail" to be moved into a location such that flexible "early escapement tabs" are moved into positions just beneath the letoff button of each of the key actions, thereby preventing a harsh "feel" or "touch" as perceived by the human player of the piano. In a second embodiment of a combination dual-mode piano, a hammer head stop rail is provided for an upright piano which intercepts the hammer head when in the electronic mode. When placed into the acoustic mode, the hammer head stop rail is rotated to a non-engaged position that is not within the normal path of the hammer travel. When operated in the electronic mode, the actuating arm is rotated such that the hammer head stop rail becomes positioned directly in the path of travel of the hammer heads of the upright piano, where they will impact directly against the stop rail. In the illustrated embodiment, the stop rail comprises a deflectable member that is coated with a sound and vibration absorbing material, such that when the hammer head impacts the stop rail, the deflectable member somewhat displaces, as the hammer head impacts against this member. The hammer head stop rail also includes a sound and vibration absorbing pad that is brought into position against the strings of the piano, thereby tending to dampen any acoustic vibration that may otherwise become induced in the strings.

摘要： In order to give piano-like key touch to a player in an electronically sound producing mode, a keyboard incorporated in a musical instrument is linked with key action mechanisms associated with hammer mechanisms, and a stopper blocks the hammer shanks before the hammers strike the strings so that noises are not mixed with synthesized tones.

摘要： In a piano mechanism, the sound volume can be effectively controlled without changing the feel of the key or tone quality. A hammer regulating button projecting from a hammer rail contacts the upper face of a catcher just before a hammer strikes a string. By restricting the string striking movement, the volume of string striking sound is controlled, irrespective of the mechanical operation of a jack or other associated transmitting components responsive to the key depressing. No cushioning material is required between hammer and string. In a piano having an electronic sound source built therein, even when the keys are depressed, the hammer can be stopped from striking strings by the provision of a hammer shank stop rail and a catcher regulating button. Therefore, without generating a string striking sound, sounds are generated from the electronic sound source. By manually turning an adjusting screw of the catcher regulating button, the position of the hammer when stopped can be adjusted. Therefore, even after repeated use, the string striking movement can be positively stopped.
摘要翻译：在钢琴机构中，可以有效地控制音量，而不改变琴键或音质的感觉。从锤子轨道突出的锤子调节按钮在锤子撞击绳子之前接触捕获器的上表面。通过限制弦线冲击运动，可以控制弦击音的音量，而不管千斤顶或其他相关联的发射部件的响应于按键的机械操作。锤和弦之间不需要缓冲材料。在其中内置有电子声源的钢琴中，即使按下按键，也可以通过设置琴槌止动轨和收音机调节按钮来将琴槌停止在击弦上。因此，不会产生串音冲击的声音，从电子声源产生声音。通过手动转动捕手调节按钮的调节螺丝，可以调节锤子在停止时的位置。因此，即使在重复使用之后，可以肯定地停止线条打击动作。

摘要： A mute piano is responsive to key movements and pedal movements so as to produce music data codes expressing the pitch of tones and pedal effect to be given to the tones in accordance with the MIDI protocols, and the damper pedal stroke is divided into a rest region, a half-pedal region and a damper-free region which are expressed by difference numerical ranges of data bytes of the musical data code: since the piano has its own individuality, the relation between the pedal position and the value of data bytes is to be calibrated; the controller of the mute piano enters a calibration mode, and optimizes the relation to the actual damper actions, thereby causing the music data code exactly to express the effect of the damper pedal to be given to the tones.
